Answer:
37
Step-by-step explanation:
Let x be the smaller number. 2x+7 is the larger number. Their difference is 22:
x+22=2x+7
x=15
So the smaller number is 15 and the larger number is 2(15)+7=37.
Answer:
Step-by-step explanation:
960 which is the area u divide by the one foot which is 144 square units to get your answer,6.66666666667
J = g + 10
j + g = 27
g + 10 + g = 27
2q + 10 = 27
2q = 27 - 10
2q = 17
g = 17/2
g = 8.50 <=== Gail has $ 8.50
j = g + 10
j = 8.50 + 10
j = 18.50....Jim has $ 18.50
Yes, because 2/4 reduces to 1/2 and so does 3/6

Probability of answering 8 or more questions correctly ;
Direct sum:
P(x ≥ 8) = p(8) + p(9) + p(10)
P(≥ 8) = 0.00038624 + 0.00002861 + 0.00000095
= 0.0004158
Complement :
P(x ≥ 8) = 1 - p(x ≤ 7)
1 - [p(7) + p(6) + p(5) + p(4) + p(3) + p(2) + p(1) + p(0)]
1 - [0.00308990 + 0.01622200 + 0.05839920 + 0.14599800 + 0.25028229 + 0.28156757 + 0.18771172 + 0.05631351]
1 - 0.99958419
= 0.00041581
